If you leave out the quotation marks when requesting data 
using odbc_result, PHP.exe crashes.

Here's an example script that crashes PHP every time 
(substitute a real DSN, table, and column of course).

<?	$wire = odbc_connect("ANY_DSN", "dba", "dba"); 
	$outcome = odbc_do($wire, "SELECT * FROM ANY_TABLE");
	odbc_fetch_row($outcome);
	$var = odbc_result($outcome, "ANY_FIELD);
?>

Note the missing quotation mark after ANY_FIELD.  That's
what causes the crash.
